Well, there are two types of ice which impede navigation - icebergs, and sea ice. Icebergs are indeed predicted to increase, glacial melting leading to greater calving rates, which then flow out of the arctic and into the north atlantic shipping lanes.
With regards to sea ice, do recognise it is going to form in quantity so long as the earth remains habitable. Extended periods of 24 hour darkness will ensure that. Warmer, shorter winters though would precipitate the loss of multi-year ice banks, so a greater fraction of ice over time would be replaced with first year, and liable to outflow.
Additionally, Newfoundland itself is not predicted to see the same warming trends as most of the rest of the world in climate change models, care of predicted increased outflow from the arctic sea cooling portions of the North Atlantic.
The ice this year is indeed an outlier, as seen in 1974, 1990, 2007, now 2017, so is earlier than expected from a cyclical perspective.
